[Signals] Signals, Errors, Event Log Help 50/10 Comcast HSI

I have had on going lag and total slow downs. I researched the signal levels and get mixed information. I am using a Router TG862G in Bridge mode to Asus N66U.

I have been getting high error counts ((These error's are after a reset yesterday)and should my upstream be reading as DOCSIS 2? I am on the 50/10.

Any input would be greatly thankfull. I don't want to go through the hassle of contacting Comcast if there is nothing to worry about.

Your downstream signal is a bit high for my taste, but within working conditions (anything between -10 and +10 is not too much of a concern). Don't suppose you have an amplifier at the beginning of the drop?

But anyways, the docsis 2 upstream channels are normal as docsis 3 still uses docsis 2 upstream modulation, but bonds multiple docsis 2 upstream channels together. So it is perfectly normal and great that you have 4 which is the max your modem can lock onto.

If you are getting t3 errors only after a reset and not 10 or more minutes after, then it is normal. At this point, I'd say it's probably maintenance that is going on with your node. If it happens longer than a couple of days, you'd want to call a tech out to see if there are any issues with your line. I assume the Asus router is set up to not drop necessary packets (firewall), but that would be my last guess for lag and slowdown.
